INTRODUCTION Ore deposits are crustal concentrations of useful elements that can be exploited at a profit. Like all crustal rocks, they consist of minerals

evaluation work3,4. involves calibration of certain ore-specific parameters. These where α is a parameter depending on the type of mineral-ization of the deposit, and which can be calibrated, and K is given by: [7] For a particular ore, c, f, g, d0 are constants. K depends

Chikki, a popular Indian traditional sweet snack prepared from peanut was enriched with protein, minerals and vitamins by incorporating soy protein isolate, calcium carbonate, ferrous fumerate, vitamin A and folic acid to meet the growing demand for health foods. The enriched nutra chikki was evaluated for physico-chemical characteristics such as moisture, texture, peroxide value (PV), fatty

Image analysis data obtained from scanning electron microscopy provided data for a detailed evaluation of the separation efficiency for various processes involving the beneficiation of particulate materials. A dry magnetic separation by a drum type magnetic separator served as a case study to visualize effects of processing of a skarn ore with a high content of cassiterite as ore mineral (~4

An indicated mineral resource is that part of a Mineral Resource for which quantity, grade or quality, densities, shape and physical characteristics, can be estimated with a level of confidence sufficient to allow the appropriate application of technical and economic parameters, to support mine planning and evaluation of the economic viability

Key ore floatability parameters (flotation rate constants and proportion of mineral in different floatability classes) can also be derived from the laboratory test flotation response. The values of these ore floatability parameters can be evaluated and compared to rank different ore types or reagent suites.

Recovery and dilution usually are interrelated; with some methods of stoping a high recovery involves contamination of the ore from the walls or capping, and often clean ore can be obtained only by leaving some ore in the mine. In open-stope mines the greatest loss of ore is that tied up in pillars left for support of the back or hanging wall.

The terms ore mineral and mineral deposit were originally applied only to minerals and deposits from which metals are recovered, but present usage includes a few nonmetallic minerals, such as barite and fluorite, that are found in the same kinds of deposit as metallic minerals. No deposit consists entirely of a single ore mineral.
